Specifications include, but are not limited to: Task 3.1 – Proposed Microgrid Infrastructure and Operations Provide a simplified equipment layout diagram and a simplified one-line diagram of the proposed microgrid, including location of the distributed energy resources (“DERs”) and utility interconnection point(s). Identity existing and planned (new) infrastructure that will be part of the microgrid. Provide a brief narrative describing how the proposed microgrid will operate under normal and emergency conditions. Provide a written description of how the microgrid will be interconnected to the grid. Will there be multiple points of interconnection with the grid? What additional investments in utility infrastructure may be required to allow the proposed MG to separate and isolate from the utility grid? Provide a written description of the basic protection mechanism within the microgrid boundary. Task 3.2 – Load Characterization Fully describe the electrical and thermal loads served by the microgrid when operating in islanded and parallel modes: Peak kW, Average kW, annual/monthly/weekly kWh, annual/monthly/weekly BTU (consumed and recovered) and identify the location of the electrical loads on the simplified equipment layout and one-line diagrams. Provide hourly load profile of the loads included in the microgrid and identify the source of the data. If hourly loads are not available, best alternative information shall be provided. Provide a written description of the sizing of the loads to be served by the microgrid including a description of any redundancy opportunities (ex: n-1) to account for equipment downtime. Task 3.3 – Distributed Energy Resources Characterization Provide the following information regarding Distributed Energy Resources (DER) and thermal generation resources that are a part of the microgrid: (i) Type (DG, CHP, PV, boiler, solar water heater etc.), (ii) rating (kW/BTU), and, (iii) Fuel (gas, oil etc.). If new DER or other thermal generation resources are a part of the microgrid, provide a written description of the approximate location(s) and space available. Identify the DERs on the simplified equipment layout and one-line diagrams. Differentiate between new and existing resources. Provide a written description of the adequacy of the DERs and thermal generation resources to continuously meet electrical and thermal demand in the microgrid. Describe how resilient the DERs and thermal generation resources will be to the forces of nature (severe weather) that are typical to and pose the highest risk to their operation (example, reduced or zero output due to snow cover over PV panels, potential flooding of low lying areas, etc.) Provide a description of the fuel sources for DER. Describe how many days of continuous operation of the microgrid can be achieved with current fuel storage capability. If additional fuel storage is required, provide a written description of needs required for this. Provide a written description of the capability of DERs including, but not limited to the following capabilities; black start, load-following, part-load operation, maintain voltage, maintain frequency, capability to ride-through voltage and frequency events in islanded mode, capability to meet interconnection standards in grid-connected mode.
